many ruby/rubygem ports: death of rubyforge.org
rubyforge.org shutdown on May 15, 2014. This commit accounts for that by doing
several things:
- Deprecate ruby that had only rubyforge.org as MASTER_SITES (and so are now
only fetchable via our cache)
- Deprecate ports that depend on those
- Update the WWW pkg-descr line that points to rubyforge.org for rubygem ports
(which are still fetchable from rubygems.org)
The next step will be to remove rubyforge.org from bsd.sites.mk, after these
deprecated ports are deleted.

ruby-prof is a fast code profiler for Ruby. Its features include:
* Speed - it is a C extension and therefore many times faster than the standard
Ruby profiler.
* Flat Profiles - similar to the reports generated by the standard Ruby profiler
* Graph profiles - similar to GProf, these show how long a method runs, which
methods call it and which methods it calls.
* Threads - supports profiling multiple threads simultaneously
* Recursive calls - supports profiling recursive method calls
* Reports - can generate both text and cross-referenced html reports
* Output - can output to standard out or to a file
